North American to UK Sizes

On our website we carry mostly UK brands because they're the ones making small bands and big cups. We sell mostly to Canadian and American women who aren't used to seeing UK sizes so these charts show the UK and North American size equivalents.

NB: Most tables you see will show a UK DD cup the same as a US E cup but we simply haven't found this to be true. Of the styles we carry a UK DD cup is the same as a North American D cup.
